fbsql_read_clob

Description

If a select statement contains BLOB and/or CLOB columns FrontBase will
return the data directly when data is fetched. This default behavior can
be changed with fbsql_set_lob_mode() so the fetch
functions will return handles to BLOB and CLOB data. If a handle is
fetched a user must call fbsql_read_clob() to get the
actual CLOB data from the database.

Parameters

If optional and not specified,
the function will try to find an open link to the FrontBase server and if no
such link is found it will try to create one as if
fbsql_connect() was called with no arguments.

Return Values

Returns a string containing the specified CLOB data.
